Controlling Factors on Condensate Production from the Eagle Ford Shale
This thesis examines the impact on recovery from shale condensate reservoirs of key properties such as porosity and permeability as well as other controlling factors that include the horizontal wells length, liquid drop out and liquid loading around the wellbore. It also addresses the possibility …

GEOCHEMICAL ANALYSIS OF THE EAGLE FORD SHALE IN WEBB AND DIMMIT COUNTIES, TX
<p>The Late Cretaceous Eagle Ford Shale of South Texas is a mixed carbonate–siliciclastic succession that serves as both a prolific hydrocarbon source and reservoir. This study integrates chemostratigraphy, mineralogical analysis, and elemental ratio proxies to reconstruct depositional environments …

Anisotropic analysis of unconventional reservoirs using rock physics model: Eagle Ford shale case study
Eagle Ford shale has been of importance in the oil and gas industry with the new advent of unconventional technology in recent years. Previous studies have shown that Eagle Ford shale is a world-class source rock. Rock physics models help characterize the elastic properties of conventional and …

Aerosol formation from oil and gas development in the Eagle Ford Shale in two different seasons
… the influence of UOGD on the air quality in the Eagle Ford Shale (EFS), a region in southeast Texas, through ambient measurements during two different seasons. Instrumentation was deployed to Karnes City, TX, located in the EFS, in the spring and fall of 2023. Instrumentation included ACSM, SEMS, …

Microseismic guided wave eigenfunction theory with application to event depth classification in the Eagle Ford shale
… and dispersion modes in a model representing the Eagle Ford Shale is then studied. High frequency guided wave energy is found to be largely confined to the Eagle Ford, and the modal energy distribution shows a nodal point in the first higher mode for events originating in the middle of the Eagle …

Petrographic and petrophysical characterization of the Eagle Ford Shale in La Salle and Gonzales counties, Gulf Coast Region, Texas
The Eagle Ford Shale is an organic-rich marine carbonate-dominated mudrock located in the Gulf Coast Region, Texas. This mudrock was deposited during the Late Cretaceous and is composed of two main members: the lower and the upper Eagle Ford, which are associated to marine transgression and …

An Exploratory Study on the Possible Effect of Hydraulic Fracturing Activities on Air Quality in the Eagle Ford Shale Region of Texas.
<h3>Eagle Ford Shale (EFS) play is one out of five major oil and gas formations in Texas, found in the South-Eastern region with approximately 30 counties. In addition to natural gas, it produces crude oil and petroleum liquids which in recent times has resulted in a surge in drilling due to a new …

Characterization of anisotropy in organic-rich shales: shear and tensile failure, wave velocity, matrix and fracture permeability
… fractures are common features in organic-rich shales. The objective of this thesis is to determine the impact of lamination and fractures on elastic properties, shear and tensile failures, and the permeability of organic-rich shales. The elastic properties of rocks determine the hydraulic …

Interpretation and Fracture Characterization of Early-Cretaceous Buda Limestone Formation Using Post-Stack 3D Seismic Data in Zavala County, Texas
… in south Texas which unconformably underlies the Eagle Ford Shale. Matrix porosity of the Buda is less than 6%, therefore natural fractures improve the potential for commercial hydrocarbon production from this tight limestone formation. This presents a challenge for producers to identify these …

Spatially resolved life cycle models for the environmental footprint of electricity generation
… new natural gas developments in the Barnett and Eagle Ford shale regions in Texas, the consumptive water impact of new natural gas development in Texas, the impact of seasonal versus ozone forecast-based pricing for power plant NOx emissions in the state of Texas, and the potential cost and air …

Investigation of Asphaltene Instability Under Gas Injection in Unconventional Reservoirs and its Impact on Oil Recovery Performance
<p>"Unconventional reservoirs, such as shale gas and tight oil formations, have become an important source of energy in recent years. However, these reservoirs often contain high levels of asphaltenes, which can lead to deposition and blockages in production wells and reduce the flow of …

Capillary pressure curve and liquid permeability estimation in tight oil reservoirs using pressure decline versus time data
Estimating oil recovery from shale is a difficult process because organic mudrocks have very low permeability (10nD - 100nD), high kerogen and clay content, a complex pore structure and low porosity (typically less than 10%). In addition, most of the pore sizes in organic mudrocks are within the …

PRODUCTION FORECASTING FOR SHALE OIL: WORKFLOW
… Different methodologies to estimate reserves for shale gas and coal bed methane have, thus far, proved to be reliable, but no simple yet accurate workflow has been generally accepted to forecast production and estimate reserves for shale oil. To fill this gap in technology, we proposed and …

DEVELOPMENT OF STANDARD OPERATING PROCEDURE WITH MODIFIED METHOD TO QUANTIFY BENZENE AND OTHER VOLATILE ORGANIC COMPOUNDS IN AIR SAMPLES USING GAS CHROMATOGRAPHY
… future research in air quality monitoring in the Eagle Ford Shale area. An SOP has been developed for the SFA Environmental Assessment Lab and details materials, lab procedures, gas chromatograph (GC) analysis, field sample collection procedures, and operation and maintenance of the GC. A modified …

Identification and Quantification of Greenhouse Gas Emissions from Oil and Natural Gas Operations Using an Aircraft-Based Mass Balance Technique
… from a field campaign conducted in the Barnett shale, Texas which quantified CH4 emissions from facilities with atypically large emissions, known as “super-emitters”, and assessed their overall contribution to basin-wide emissions. Calculated emissions were compared to inventory estimates and …
